Understanding the Chemicals In Your Hot Dog

In the upside-down world of labeling, hot dogs can be “all-natural” even if they contain nitrates.

Here's what fireworks, chemical fertilizers, and frankfurters have in common­: They all contain nitrogen compounds. Sodium nitrates, which are used as a preservative in standard hot dogs, have inspired a decades-long scientific debate over their possible health risks to humans. Perhaps you'd like to keep tabs on how much nitrate is in the hot dogs you're scarfing this summer­­. Unfortunately, you can't.

Here's the thing: Even uncured, “nitrate-free” meats contain healthy doses of nitrates. So do many raw vegetables and most municipal water supplies. In fact, "natural" meats can contain even more nitrite than your standard heavily-processed bacon strips and hot dogs.

(Celery juice is often used in the meat.)
